Thrummingbird is a 1/1 for 2 mana with flying that allows you to proliferate whenever it deals combat damage to a player.

Goatnapper allows you to steal your opponents goats. And Sanctuary Cat is another cute card.

Dismember, Gideon Jura, Sunblast Angel, Gideon's Lawkeeper, and Gideon's Avenger aren't legal in standard.

Thanks for the suggestion, but Moment of Silence is cheaper and more effective.

Mageta the Lion can use Wrath of God effecting every creature but himself at the cost of tapping him, paying 2WW, and discarding two cards.

Darksteel Plate is cheap, gives indestructibility, and can be moved from creature to creature.

Thanks, I'll find a way to add that in. Now that you mention it, Moment of Silence would be good too.

Could use Karrthus, Tyrant of Jund and Kaalia of the Vast. If you replaced Vorosh, the Hunter with Teneb, the Harvester you could make this deck 4 colored instead of five, which would be a huge advantage.

Dismember, Gideon Jura, Sunblast Angel, Gideon's Lawkeeper, and Gideon's Avenger aren't legal in standard.

Could use Ajani's Pridemate, Ajani Goldmane, Serra Avatar, Ageless Entity, Beacon of Immortality, Armadillo Cloak, Behemoth Sledge, Heroes' Reunion, Felidar Sovereign, Boon Reflection, Rhox Faithmender, Rest for the Weary, Lifelink, Soul Warden, Essence Warden, Pride Guardian, Wall of Hope, Wall of Reverence, Cradle of Vitality, and Wall of Essence.

Mishra is a great card. This deck could use Tinker and Tolarian Academy, Buried Ruin, and Academy Ruins.

Needs Rhys the Redeemed and Rhys the Exiled. Adding some things with proliferate such as Contagion Clasp or Contagion Engine would allow you to add to Immaculate Magistrate's counters and achieve Nissa's ultimate ability faster. Otherwise its a great deck.

Thanks, I'll consider it.

Could use Necrotic Ooze and Tarmogoyf.

Amazing deck. Risky, but amazing. I'd advise adding either Lightning Greaves or Swiftfoot Boots, and Darksteel Plate to this deck so that your Laboratory Maniac won't be removed. Also, you need to add another Laboratory Maniac to this deck.

This deck is going to do great once the new mythic rare land that you can return to it your hand and pay 3 to search your library for a gate card and put it into play comes out in Dragon's Maze. The card also says that if you control 10 or more gates with different names you win the game.

Consecrate land seems a bit unnecessary. This deck could also use Wrath of God.

Good deck. Needs Trepanation Blade, Sword of Body and Mind, and Geth Lord of the Vault. The Witchbane Orb in your sideboard should be replaced by a Leyline of Sanctity. Also, if you aren't going to run any basic lands, your Drowned Catacombs, Glacial Fortresses and Isolated Chapels could easily be replaced by guildgates.

Gutter Grime would allow you to replace your oozes when they died.

Needs Clone, Infinite Reflection, and Cackling Counterpart. Adding Momir Vig would allow you to find the biovisionaries faster.You should probably make a sideboard. Love the idea behind this deck, if you could find a way to add protection abilities, shroud, or hexproof to this deck it would be invincible. Also could use Primordial Hydra.
